My hyper maintained 2019 QX60 will need the transfer case and rear differential fluid changed in 3k kilometers, I currently have 80W90 in the transfer case and a semi-synthetic GL5 75W90 in the rear differential. Can I standardize these 2 oils with just using the GL5 75W90 for both the transfer case and rear diff?
I do this service every 35k kilometres - which works out to 2 years. The transfer case only holds 300ml and the rear diff about 500ml, so having 1 bottle of each different oil is sort of annoying.
Would you do it?
